Sporting a classic tube shape, Strike King's Coffee Tubes are enhanced with real coffee bean granules and coffee bean oil to give the tubes an earthy tinge and a naturally strong scent/taste big bass are eager to slurp up. Not only does the coffee scent/flavor entice and encourage fish to hold the bite longer, it also works to mask human scents. They are salt-impregnated too! The 4-1/2'' Coffee Tube has a solid head and a hollow body. Great on a Texas rig for flipping and pitching.
